Embodiment 1

[0053] Example 1: Preparation of spray active ingredients

[0054] Weigh 900g of red stone fat, 1200g of isatidis, and 1200g of astragalus; soak the isatid root and astragalus in 8 times of water, decoct in water for 30 minutes, precipitate with 70% ethanol, filter, and concentrate by rotary evaporation; soak the red stone fat with 5 times of water, and then add isatis root and the extract of Astragalus membranaceus, fully stirred, put the above liquid into a colloid mill, grind and refine it, and pass through a 325 mesh sieve to obtain the active ingredient of the spray.

Embodiment 2

[0055] Example 2: Preparation of spray active ingredients

[0056] Weigh 1000g of red stone fat, 1500g of isatidis, and 1500g of astragalus; soak the isatid root and astragalus in 10 times of water, decoct in water for 20 minutes, precipitate with 70% ethanol, filter, and concentrate by rotary evaporation; soak the red stone fat with 5 times of water, and then add isatis root and the extract of Astragalus membranaceus, fully stirred, put the above liquid into a colloid mill to grind and refine it, and pass through a 300 mesh sieve to obtain the active ingredient of the spray.

Embodiment 3

[0057] Example 3: Preparation of spray active ingredients

[0058] Weigh 1100g of red stone fat, 2000g of isatidis root, and 2000g of astragalus; soak the isatid root and astragalus root in 10 times of water, decoct in water for 30 minutes, precipitate with 70% ethanol, filter, and concentrate by rotary evaporation; soak the red stone fat with 3 times of water, then add isatis root and the extract of Astragalus membranaceus, fully stirred, the above liquid is put into a colloid mill to grind and finely pass through a 400-mesh sieve to obtain the active ingredient of the spray.

Abstract

The invention relates to a method for preparing a spray for preventing emerging respiratory tract infectious diseases, and belongs to the technical field of preparation methods of Chinese medicinal preparations. The preparation method comprises the following steps of: performing water boiling and alcohol precipitation on indigowoad root and astragalus, mixing, filtering, evaporating rotatably and concentrating; adding water into halloysit for dipping, adding indigowoad root extract and astragalus extract, and stirring fully; putting the liquid into a colloid mill for grinding and refining, and sieving with a 325-mesh sieve; stirring the sieved liquid under heating, cooling to room temperature, adding sodium carboxymethylcellulose and sodium benzoate, and stirring fully to form suspension; and adding the suspension into a medicinal plastic bottle with a quantitative spray pump to obtain the spray for preventing the respiratory tract infectious diseases. The spray prepared by the method has the advantages that the spray does not become invalid due to the cirus variation, does not produce drug resistance, prevents unpredictable new respiratory infectious disease, effectively cuts off the propagation path, and protects the susceptible population.

Description

technical field [0001] The invention belongs to the technical field of traditional Chinese medicine preparations, and in particular relates to a preparation method of a spray for preventing emerging respiratory infectious diseases. Background technique [0002] In recent years, changes in the environment and climate, as well as the evolution and mutation of microorganisms have led to frequent occurrences of new and sudden infectious diseases around the world. Their unpredictability, danger and terror have brought great challenges to national health care. Among them, the outbreak of airborne new respiratory infectious diseases has caused particularly serious harm, from the outbreak of SARS (severe acute respiratory syndrome, severe acute respiratory syndrome) in 2003 to the outbreak of avian influenza and H1N1 influenza virus in recent years From the perspective of infection incidents, my country is facing an increasingly serious risk of sudden outbreaks of new respiratory inf...
